Abstract
The relay has a permanent magnet (7) which provides an attractive force used to hold the armature (6) in place while a fault current through the coil (10) on the U-core acts to oppose the permanent field and allows displacement of the armature under the pull of a spring (8). The arm (5a) of the core acts as a pivot on the contact surface (6a) of the armature or the contact surface and both poles of the core are covered with carbon in the form of diamond. The layer is 0.5-2 mu m thick and has a structure which is 2/3 diamond. The deposition is achieved by epitaxy chemical vapour deposition.
